Category: Installation Guides

Reading Time: 6 minutes

A smart deadbolt adds convenience, security, and remote access to your home. Whether you're upgrading from a traditional lock or installing a smart lock for the first time, this guide walks you through the full installation process — removal, mounting, wiring (if applicable), pairing, and testing.

Tools & Materials Needed

• Phillips screwdriver

• Flathead screwdriver

• Tape measure

• Smart deadbolt kit

• AA or CR123 batteries (depending on model)

• Optional: drill + drill bits (if modifying door alignment)

Safety Notes

• Do not overtighten screws — it can damage the lock mechanism.

• Ensure your door is properly aligned before installation.

• If your door is warped or rubbing, fix alignment before installing the smart lock.

Step 1: Remove the Old Deadbolt

1. Unscrew the interior thumb‑turn plate.

2. Remove the two long screws holding the deadbolt together.

3. Pull the interior and exterior pieces off the door.

4. Remove the old latch from the door edge.

Step 2: Install the New Latch

1. Insert the new latch into the door edge.

2. Ensure the latch faceplate sits flush with the door.

3. Secure it with the included screws.

4. Confirm the latch moves smoothly when extended and retracted.

Pro Tip: Most smart locks require the latch to be in the extended position during installation.

Step 3: Install the Exterior Keypad

1. Feed the cable through the door hole.

2. Align the keypad flush against the exterior side of the door.

3. Ensure the tailpiece (metal bar) goes through the latch correctly.

Step 4: Install the Interior Mounting Plate

1. Hold the mounting plate on the inside of the door.

2. Connect the cable from the keypad to the interior connector.

3. Align the screw holes and secure the mounting plate.

4. Do not overtighten — the lock should sit flat without bending the door.

Step 5: Attach the Interior Assembly

1. Place the interior lock body onto the mounting plate.

2. Secure it with the included screws.

3. Insert the batteries.

4. The lock should power on automatically.

Step 6: Calibrate the Lock

1. Follow the on‑screen or voice prompts.

2. The lock will test the latch direction and bolt movement.

3. Ensure the bolt extends and retracts smoothly.

Step 7: Set Up the App

1. Download the manufacturer’s app.

2. Create or log into your account.

3. Add the lock using Bluetooth, Wi‑Fi, or a hub.

4. Set up:

• User codes

• Auto‑lock

• Notifications

• Remote access (if supported)

Step 8: Test the Lock

1. Lock and unlock using the keypad.

2. Test the app controls.

3. Confirm the door closes and seals properly.

4. Check that the bolt fully extends into the strike plate.

• Keypad responds quickly

• App control works reliably

• Door alignment is correct

• Auto‑lock and alerts function properly
